Ronny,
Working with all of the pgs shown in the "ceph health detail", I ran below for
each PG to export.ceph-objectstore-tool --op export --pgid 0.1c --data-path
/var/lib/ceph/osd/ceph-0 --journal-path /var/lib/ceph/osd/ceph-0/journal
--skip-journal-replay --file 0.1c.export
I have all PGs exported, except 1... PG 1.28. It is on ceph-4. This error
doesn't make much sense to me. Looking at the source code from
https://github.com/ceph/ceph/blob/master/src/osd/osd_types.cc, that message is
telling me struct_v is 1... but not sure how it ended up in the default in the
case statement when 1 case is defined... I tried with --skip-journal-replay,
fails with same error message.ceph-objectstore-tool --op export --pgid 1.28
--data-path /var/lib/ceph/osd/ceph-4 --journal-path
/var/lib/ceph/osd/ceph-4/journal --file 1.28.exportterminate called after

Then wrote a simple script to run import process... just created an OSD per PG.
Basically ran below for each PG.mkdir
/var/lib/ceph/osd/ceph-5/tmposd_0.1c/ceph-disk prepare
/var/lib/ceph/osd/ceph-5/tmposd_0.1c/chown -R ceph.ceph
/var/lib/ceph/osd/ceph-5/tmposd_0.1c/ceph-disk activate

/var/lib/ceph/osd/ceph-5/tmposd_0.1c/whoami) --journal-path

/var/lib/ceph/osd/ceph-5/tmposd_0.1c/systemctl start ceph-osd@$(cat
/var/lib/ceph/osd/ceph-5/tmposd_0.1c/whoami)
Sometimes import didn't work.. but stopping OSD and rerunning
ceph-objectstore-tool again seems to help or when some PG didn't really want to
import .
Unfound messages are gone! But I still have down+peering, or
down+remapped+peering. # ceph health detailHEALTH_ERR 22 pgs are stuck inactive
